Trusted Dissemation of Data in Opportunistic Network

Executive Summary

With the rapid evolution of network diversity and the development of short range wireless communication technologies, a new network known as opportunistic networks emerges, this kind of network falls into two fields-Mobile Ad-hoc NETwork (MANET) and Delay Tolerant Network (DTN). Opportunistic network thus comprises the methods and features of Delay or Disruption Tolerant Network. They are very much suitable to support the pervasive networking scenario, in which a huge number of devices carried by users and embedded in the environment communicates wirelessly without requiring any pre-existing infrastructure. By enabling end to end connectivity and hence communication without requiring complete paths, opportunistic networks are much closer to real pervasive networking scenarios, with respect to the legacy MANET paradigm.
